RAZOR-STROPPING DEVICE.

Specification of'Letters Patent. Patented Dec, 14, 1909. 7

Application filed July 17, 1907. Serial No.384,153.

To all whom'it may concern:

Be it known that I, CHARLES FREDERICK BnNED1oT, a citizen of the United States, and a resident of the borough of Brooklyn,

"in the county of Kings and State of New shows an enlarged left hand end view of Fig. 1, Fig. 3 is a top view of Fig. 2, Fig. 4 represents a section of Fig. 3 on the line 4, 4, Fig. 5 shows a section as on the line 5, 5 of Fig. 3.

The invention is shown ,to con'iprise a holder having the side frames 20, connected by the upper tie rod 21 and the lower tie rods and guides 22. A pair of upper guide rollers 23, and central guide rollers 24 extend between and are journaled in the frames 20. In the upper ends of the side frames 20 are formed guide openings 29, which support a blade carriage 30. The said carriage comprises spring jaws 31, having a flanged roof 32, from which roof extends a bar constituting the cross heads 33. The said bar is shown completely over the flanged roof, but said construction need not be followed. From the top of the said bar extends asupporting plate 34, with the end brackets 35.

The latter are connected by a spring 36,

having an opening 37. A presser plate-40 with the end lugs 41, straddling the brackets 35 is located above the said supporting plate. A screw 41, with a circular nut 42 extends from the presser-plate 40 to and through the opening 37 in the spring 36. A bail 43 extends from the upper tie rod 21.

The razor strop 44 is located between the plate 34 of the carriage 30 and the presser plate 40. The strop being sufliciently gripped to allow it to carry the carriage to one side or the other of the holder, by adjusting the nut 42, to bear against the spring 36, and at the same time allowing the strop to be pulled through the opening between the supporting plate 34 and the presser plate 40, when the said carriage is in position at one side of the frame. The razor strop leads over the upper guide rollers 23 then around the inner sides of'the central guide rollers 24 and finally between the pairs of lower tie rods and guides 22.

A razor blade 50 is secured inthe spring jaws 31 as shown.' To use the invention an operator suspends the holder by means of the bail, therazor being clamped in the jaws of the blade car riage 30 and then alternately pulls the ends of the-strop, through the opening between the supporting plate and presser plate, by virtue of which the carriage will be moved to the opposite sides of the holder, so that each side and the edge of the blade of the razor will be brought to bear against'the strop as the latter is being pulled by the operator.

' Having described my invention, I claim: 1. In a stropping device the combination of a 'holder, a blade carriage movably supported in the holder, a strop guided in the holder and located over the carriage, a presser plateover the strop, means to bear said plate against the strop with various amounts of pressure to conneetthe strop to the carriage, and at the same time allow the strop to be pulled through the holder. v

2. In a stropping device the combination of a holder, a pair ofside frames having guide openings in the holder, a reciprocating carriagesupported in said openings, means to secure a blade to the carriage, a

strop over the carriage and guided in the frame, a presser plate adjustably located over the carriage, a spring connected. up with the carriage over the presser plate, means toexert the tension of the spring to the presser plate, so as to grip the strop. between the plate and the carriage with sufiicient pressure to reciprocate the carriage, when the directions of the movements of the strop are reversed.

3. In a stropping device the combination of a holder, a pair of side frames having guide openings in the holder, a carriage supported in' said openings, jaws extending from the carriage to support a blade, guides extending between the frames, a strop hearing on the roof of the carriage and against said guides so as to enable said blade to bear against said strop at opposite sides of the device when the-strop is reciprocated, brackets extending from the upper portion of the carriage, a presser plate gulded by said brackets, a spring connecting the ends of the rollers andagainst the central guide rollers, and passingbetween each pair of thelower guldes and he rods, brackets extending from E strop between the carriage and presser plate,

' brackets, a screw extending up from the 5 presser plate, a nut on the screw to bear up ,against the spring and thereby grip tlre to alternately move the carriage acrossythe frame when a reciprocating the strop, the

blade alternately bearing on the strop on the opposite sidesof the device.

4 In a stropping device for a razor the combination of a holder, a pan of side frames having guide openings in the holder a bailv extending from the frames, a blade .carrlage 1n the holder, crosseheads extending from the carriage and supported in'said openings, spring aws extending from the carriage to sup .orta razor blade, upper guide rollers an central guide rollers ]O1l1 naled in said frames, two pairs of lower guides and tie rods extending between the frames, a strop bear ng on the top otthe carria e extendin over the u er 'uide strop, a screw extending up from the presser plat-e through an opening in said spring, a nut on the screw to .bear up against the spring and-thereby grip the strop between the blade carriage and said presser plate, to

alternately move the carriage across the frame when reciprocatlng, the blade bearing alternately on the strop at opposite sides of v the device.

. Signed at the borough of Manhattan in the county of New York and State of New York this 12th day of July A. D. 1907.
